I bought these trousers for use when with the camera and video camera.
Mainly for standing around in windy and wet weather.
These trousers have an elasticated waist but no drawstring to tighten them.
Well sized the go up too XXL (U.K size)

Definitely waterproof and wind proof.
Silent when being worn and when walking in them. (I know people like swishy trousers.)
Hem at the bottom fastens with poppers to close round boots etc.
Maybe not the cheapest over trousers but should last for a decent period
